Your portable writer's desk.

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Inkbreaker is a writing studio. Draft the book, build the world it lives in, and get an honest read on the prose, all in one place. The editor is built for real work: fiction, poetry, screenwriting, and long-form nonfiction, each with its own tools and formatting. Your writing saves as you type and keeps working offline, so a dead signal never costs you a sentence. Add images, keep versions, and export to EPUB or Word when the draft is ready to leave. The writing engine gives you a real read on your prose. It shows you what is actually on the page: pacing, sentence rhythm, filter words, passive voice, dialogue balance, adverb load, and more. It tells you what you wrote. It never writes for you, and nothing you write is used to train a model. The words stay yours, and Proof of Authorship records that a piece was composed in the editor rather than pasted in. Worldbuilding sits beside the draft instead of in another app. Keep characters, locations, factions, and events in a World Bible that links straight into your prose. Draw interactive maps with pins and distance scales, lay out timelines, chart who knows whom in a relationship web, and invent a language with its own phonology, lexicon, and a script you can actually type. The Continuity Sentinel watches for contradictions as the world grows. Inkbreaker is full of writers, not an audience. Join a chapter and write alongside people who show up, run sprints, swap drafts in a critique circle, enter competitions, and co-write with track changes and inline comments. When the page is blank, short daily exercises are matched to what you are working on, with a progress report that tells you whether you are actually getting better. Inkbreaker Pro unlocks unlimited prose readings, the full worldbuilding suite, unlimited exercises, and the whole tool shelf. Subscriptions renew automatically until cancelled, and can be managed in your device account settings.

Also new: screenplays in true screenplay format, forms for your site, passkeys and two-step sign-in, and writing with no connection that syncs when you're back online.
